B-2 DIMENSIONS B-2.1 Procedure Take each pantie constituting the Lay it flat on a table. Remove test sample. by hand all 5 creases and Measure the 0.5 cm. wrinkles without dimensions correct distorting it. to the nearest B-3 DIMENSIONAL CHANGES ( DUE TO RELAXATION ) B-3.1 Marking of Test Specimens B-3.1.1 Take a pantie from the test sample. Cut from it a test specimen measuring approximately 10 cm x 10 cm in such a way that the two ~of its sides are parallel in the direction of wales and the other two parailel in the direction of Mark the direction of wales and courses. courses on the test specimen. IS 14320 : 1995 Mark centrally on the test specimen, by means of indelible ink or a fast dyed cotton sewing thread, an area 5 cm x 5 cm with two of its sides in the direction of wales and the other two in the direction of course. Spread this test specimen on a flat smooth surface, carefully removing by hand all creases and wrinkles. Within this area, mark four pairs of marks, two pairs each in the wales direction and the courses direction in such a way that the distance between each pair of marks is the same. B-3.2 Procedure B-3.2.1 Place test specimen on a glass plate and carefully remove by hand all creases and wrinkles without distorting it and place the other glass plate on the test specimen. Measure, correct to the nearest millimetre, the distance between each pair of marks separately. B-3.1.2 and creases and place the other glass plate on the test specimen. Measure correct to the nearest millimetre, the distance between each pair of marks separately. B-3.2.4 Calculate, separately, the percentage dimensional change both `in the direction wales and courses by the following formula: s_ of of `OOx(a-b) a where a = S = dimensional change, percent; the dista:lce bztween a pair of marks ( along the wales or courses as the case may be ) before soaking; and b = the distance between the same pair of marks after soaking. B-3.2.2 Lay the test specimen flat in a tray of suitable size and of depth of minimum 10 cm. Soak it under a head of 25 mm of water containing 0.5 percent suitable wetting agent at 30 to 35°C for 2 hours. Drain out the water and remove the test specimen carefully SO that it is not stretched and lay it flat on a smooth surface. Remove the excess of water by absorbent material and dry it at room temperature. B-3.2.3 After drying, condition the test specimen to moisture equilibrium in standard atmosphere. if needed ( see B-1.1. ). Place it on the glass plate, carefully remove all wrinkles 8-3.2.5 Calculate separately the dimensional change between the two pair of marks in the direction of wales and in the direction of courses and calculate the average dimensional change in each direction. B-4 WALES AND COURSES Take a pantie and lay it fiat on a table. Remove all wrinkles and creases without distorting it. On one side of the test specimen, count with the help of a pick glass or a magnifying glass, the number of wales and courses in 10 cm at three different places in the test specimen and calculate the average number of wales and courses per dm. 6 Boreao of Indian Stsodardr BXS is a statutory institution established under the Bureau of Indian promote harmonious development of the activities of standardization, certification of goods and attending to connected matters in the country.
